"Let us come into his presence with thanksgiving..." (Ps. 95:2a). God isn't looking for a great sacrifice to impress Him; "...the sacrifices of God are a broken spirit." "For you will not delight in sacrifice or I would give it; you will not be pleased with a burnt offering" (Ps. 51:16-17). You may feel a cleavage betwixt you and the Lord and the only thing you might need to do is to offer a sacrifice of thanksgiving ("Enter his gates with thanksgiving, and his courts with praise! Give thanks to him, bless his name!" (Ps. 100:4). "Give thanks to the Lord, for he is good" (Ps. 107:1).
Who glorifies God? "The one who offers thanksgiving as his sacrifice glorifies me..." (Ps. 50:23).
Remember the sobering words of Paul about those who were not thankful: "For although they knew God, they did not honor him as God or give thanks to him..." (Rom. 1:21a). Everyone has a treasure chest to thank God for in spite of his circumstances: I recall the man who felt sorry for himself because he had no shoes until he saw a man without any feet. Looks like we have no excuse. "Bless the LORD, O my soul, and forget not all his benefits" (Ps. 103:2).
Conclusion: "What shall I render to the Lord for all his benefits to me?"--being thankful is a start-- (Ps. 116:12). Soli Deo Gloria!
